This is a demo that shows mean-shift based tracking
You select a color objects such as your face and it tracks it.
This reads from video camera (0 by default, or the camera number the user enters
Usage:
./camshiftdemo [camera number]
Hot keys:
ESC - quit the program
c - stop the tracking
b - switch to/from backprojection view
h - show/hide object histogram
p - pause video
To initialize tracking, select the object with mouse
init done
opengl support available
pure virtual method called
terminate called without an active exception
